We use semiclassical Monte Carlo simulation to investigate the effect of magnon scattering on spin relaxation in Germanene. The spin relaxation length (SRL) in germanene attains a peak value at a magnon energy of 1.5 meV and then saturates to a value of 520 nm for higher values of magnon energy. Germanene is found to have lower peak spin relaxation length than graphene. Temperature value of 4 K is used for the simulations and D'yakonov-Perel (DP) and Elliott-Yafet (EY) spin relaxation mechanisms are taken into account.
